In this paper, a robust and fast approach to lip detecting and lip-reading is presented. The approach combines the information of lip color with the geometrical features of lips in human face. This technique makes it possible to derive lip regions in real time under regular illumination conditions. The experimental results with more than 2000 images have shown that the approach to locating lips is very efficient both in locating speed and locating accuracy. Recognition tests were conducted on Chinese phrases. The approach achieved an ccuracy of 90% for speaker dependent recognition task.
